I also remove the dog-leg from the butterfly spring and rough-in tension. I ground an old pair of Iineman pliers to a mating curve creating wire bending pliers. This removed the dog-leg and makes a nice curve. Otherwise when you weaken the spring, the contact point is on the backside of the teflon nut; this places it on the frontside - further away from the coil. I plan on getting a force gauge to measure a regulated set of rep levers and flanges to ascertain their graduated tensions across the keyboard so the process can be speeded up prior to installation. I also modify the spring and install a #3 fillister head machine screw to made them more easily adjustable.
